Thanks guys. I took my first readings yesterday before reading this, so I only did one reading per leaf(s).
My process:
Took four leaves (who knew you could do it with just one!? LOL!) midway up the plant from different colas. Used VonDs method with mortar and pestle and two spoons, (rep) and got two good drops of juice for each plant. Followed procedure and did one plant at a time, cleaned, sterilized, etc.
I did not get a clear cut line, but definitely a demarkation between the "blue" and "white".
Plants are in HB soil. Day 37 of 12/12 Have had both Cat drenches and will get energy tomorrow or Thurs.
Pineapple Trainwreck - 13-14 range
Gold Leaf - 12-13 range
Next testing with be with one leaf, tested at least twice. Other suggestions?
